can't plot ylab in graph

I am sure I am missing something obvious as usual, but in the following graph I can't plot ylab. Ignoring unimportant details, I am plotting one instance of truehist() and one instance of curve() on the same graph. Truehist() won't let me pass the ylab argument. It gives me the error Error in plot.default(xlim, c(0, ymax), type = "n", xlab = xlab, ylab = "", : formal argument "ylab" matched by multiple actual arguments I don't understand the error. I looked at the help page for truehist(). The xlab argument was present but the ylab argument was missing.
Right, so why do you think it accepts `ylab'? There seems to be a crop of people asking questions or sending bug reports who think `xlab' and `ylab' are graphical parameters, but that are actually arguments to title() which plot.default passes through. What you can do is call title(), as in library(MASS) truehist(rnorm(100)) title(ylab="some y label")
